We have numerous customers using Cisco / Linksys RV042 VPN firewall devices to connect to a central location via VPN tunnels. We have noticed that if there is an interruption to any of the tunnels, the RV042 v2 devices will re-establish the tunnel automatically, however the RV042 v3 devices will typically fail to automatically re-establish the connection and will usually require somebody to repower the RV042 or for somebody to clear the crypto session from the central router and then manually connect the tunnel from the RV042's VPN menu.
One of my colleagues setup two RV042 v2 devices for a site to site VPN for a customer and it worked fine. At some point they replaced one of the RV042 devices with a v3 device and since then they are having the same issue.
Has anybody else experienced this? Is it a known issue? Note: We have this problem with several different version of the RV042 v3 firmware including the latest (4.2.1.02).
